CONVERTING WINDOW SASHES INTO REVOLVlNG SASHES OR FAN-LIGHTS, 8L0.

SPECIFICATION forming part of Letters Patent No. 351,146, dated Oetoberl), 1886.

Application filed Novemberfi, 1883. Serial No. 110,997.

To all whom it may concern.-

Be it known that I, Bonner ADAMS, a subject of the Queen of Great Britain, residing at No. 7 Great Dover Street, Southwark, in the county of Surrey, England, engineer, have invented certain new and useful Improvements in Apparatus for Instant Conversion of Verti- (ally-Sliding \Vindow-Sashes into that of Bevolving Sashes or Fan-Lights, and held open at any height or angle for ventilation and other purposes, but more especially for the prevention of accidents and loss of life while cleaning the same, (for which I have obtained a patent in Great Britain, No. 912, hearing date March 3, 1881,) of which the following is a specification.

My invention applies to windows with vertically-sliding sashes hung with eords,pulleys, and sash-weights, the external cleaning and re pairing of which are frequently attended with serious and fatal results.

Now, the object of my invention is to construct windows with such appliances and arrangements that the sashes may not only be raised and lowered in the usual manner, but may also be made to revolve or open on centers or bolts, pins, or pivots, after the manner of an ordinary fan-]ight, and may be also held open at any height or angle in order to facilitate cleaning. and repairing either side of the window-sash without danger, and also for purposes of ventilation, &c.

In applying this invention to windows fitted with beads I make the beads movable into grooves or otherwise by links, eccentrics, levers, or other suitable arrangements. At or near the center of gravity of each sash I provide suitable support on each side as working centers, upon which centers the sashes can be made to revolve or pivot, and be kept in any desired position in the sash or frame, and also placed at any desired height.

And in order that my said invention may be more clearly understood, the accompanying drawings are hereby referred to, in which similar letters of reference indicate similar parts.

. Figure 1 is a perspective View of a window fitted in accordance with my said invention. a a is the window-frame. b b are the sashes. b (in dotted lines) represents the upper sash partially revolved on its centers and practi- (No model.) Patented in England March 3, 1881, N0. 91!.

I I I cally acting as a fan-light. At 0 c c c are four holes with sliding covers. The usual balanceweights are used, as shown in the figure.

Fig. 2 is a side view of Fig. 1, except that the sashes are shown at right angles to the frame. The top sash is lowered down and the bottom sash raised near the top. Both sashes can be placed together at once, if desired, at any height, and when raised together to the top great facility is afforded for passing goods into or out of the room.

Fig. 3 is a sectional plan (on a larger scale) on the line (I c of Fig. 1. f is a view of part of the top of the lower sash, and f is part of the upper-sash stile in section. 5 g are the sash-lines; h h, the sash-weights in the boxes. 71 i are plate-tongues or metallic guides fitting into grooves kin the sash-bars, as shown, which grooves are deep enough to completely receive the said tongues or guides i i when looked back, and which tongues, when placed in the position shown in Fig. 3, enter the grooves k k, which are formed in the side of the box, as shown. These tongues guide the sashes vertically and prevent draft when in that position, and while these tongues are thrust out, as shown, the sash cannot swing upon its center. WVhen, however, these tongues are drawn back entirely into the grooves the sash is free to revolve.

Fig. 4 is an elevation to an enlarged scale of parts of Figs. 1 and 3. f is the upper-sash stile. m m are two metallic bearings sunk into the sash-stile, as shown. One end of the lever or link 0 Works upon a pin or fulcrum, a, fitted in m. The other end of 0 works upon a pin, a, which is attached to the tongues or guides i 73. Below this, and fitted to m in the manner shown, is a cam, 0, having a square keyhole, 0, for the insertion ofa square key. This cam has a curved slot, 1), (on a radius having 0 as the center,) which slides upon and actuates a pin, 0 It also slides against another pin, 0 for which purpose it is cut to a radius from the same center 0. The pins 0 and c are fitted in the same manner as a to the slides or guides i i. \Vhen the cam c is turned, the pin 0 is at the upper part of the slot and the pin 0 is in contact with the curved edge of the cam. The

I effect of this movement is to forcibly retain the guides or tongues c i in the position shown in Fig. 3, from which position they cannot be upon the center-pin 19 removed exceptby turning the earn the reverse way. \Vhen this is done with the key, 0 is released, the tongues it are raised and thrown back by the cam c and link 0, so as to leave the groove h, Fig. 3, entirely. "When this has been done, the sash is free to swing This pin I prefer to support in a metal bearing, 12, as shown,and which pin is strongly fitted to the sash stile and also to the cord-holder q, to which the cord 9 is attached. This cord-holder consists of a rectangular block, q, of suitable length, sliding freely in the groove is on each side of the window, and to which the end of the cord 9 is attached, the latter passing over pulley r in the ordinary manner.

Fig. 4 is a detail view of the cord-holder q removed from the casing, showing the sash journal or center-pin 1) mounted ther on and the cord g attached thereto.

Having described my invention, what I claim is- 1. The combination, with a window-casing having groove k, and a cord-holder, q, working in said groove, of a window-sash pivoted in said cord-reeeiver and having groove 7c, the movable guides 1; 12, having pins 0 c and the pivoted cam 0, having slot 12, substantially as described.

2. The combination, with a Windowcasing having groove 7c, and a cord-holder, q, working in said groove, of a window-sash pivoted in said cord-receiver and having groove is, the movable guides i 5, having pins 0 0 the pivoted cam 0, having slot 1), the pins a n, attached, respectively, to the window-sash and guides 73 i, and the link 0, pivoted to pins n n, substantially as described.-

. In testimony whereof I have hereto set my hand this 20th day of October, 1883.
